feat(UI): Refactor full player layout and build configurations

- In `build.gradle.kts`, set the debug signing configuration for the release build type.
- In `full_player.xml`, reorder the media control and playback speed buttons.
- In `layout-w600dp-land/full_player.xml`, clean up redundant layout attributes for the album cover card view.
